Abstract EN
Due to the principle error caused by the Earth’s sphere model in transverse polar navigation, the ellipsoid model is usually used for transverse transformation.
In order to avoid the complex transverse transformation of the ellipsoid model, a virtual sphere model, which can simplify the transformation of the ellipsoid model, is constructed in this paper.
With the requirements of high accuracy and long-time navigation for AUV in the polar region, the integrated navigation scheme of SINS/DVL, which is based on the virtual sphere model, is proposed.
The proposed method can improve the navigation accuracy and suppress the oscillation error.
The error equations of transverse SINS are established based on the virtual sphere model.
Then, the transverse SINS/DVL integrated navigation algorithm is derived according to the new error equations.
The simulation results show that the navigation accuracy of the proposed method is equivalent with the traditional ellipsoid model method and is better than that of the traditional sphere model method.
However, the complexity of the proposed method is simpler than the traditional ellipsoid model method.
Moreover, it is verified that the navigation accuracy of SINS/DVL integrated navigation system based on the virtual sphere model meets the requirements of AUV.
